[Piglit] [PATCH] arb_get_texture_sub_image-errors: Fix expected error values

[Eduardo Lima Mitev]

glGetTextureSubImage() and glGetCompressedTextureSubImage() return
GL_INVALID_VALUE instead of GL_INVALID_OPERATION when the 'texture'
argument does not correspond to an existing texture object.

>From OpenGL 4.5 spec PDF, section '8.11. Texture Queries', page 236:

    "An INVALID_VALUE error is generated if texture is not the name of
     an existing texture object."
